關(guān)于冬天的動物的英語美文篇一
Hibernation
Hibernation is more than sleep. It is a very deep sleep. The animal's temperature drops to just over zero centigrade, and its heart beats very slowly. People who find hibernating animals asleep often think that they are dead: the body feels very cold, and the creature may breathe only once every five minutes. A hibernating animal cannot feel any pain. You can touch it, or even pull its tail, without causing it to move or wake up. In its hibernating state it can even live in a poisonous atmosphere for a long time without any ill effect.
Hibernating in this way, the animal can sleep all through the winter. You might wonder how it manages to live without eating for so many months. The answer lies in two facts. The first is that it has stored supplies of fat in its body during the summer and autumn. The second is connected with the main use the body makes or rood——to supply the energy for movement. We have seen that hibernating animal reduces movement to far below the ordinary level. Even the movements or the heart and lungs are greatly reduced. The animal hardly makes any movement, hardly use any energy, and hardly needs any rood.
Some animals, including some bears only hair hibernate. That is to say, they sleep during the winter, but their sleep is not deep and their body temperature does not drop, as they are warm blooded animals. In the antumn the bear eats and eats and becomes very rat. His hair grows longer. Soon he has a thick covering or rat and fur. In November he rinds a place to lie down and goes to sleep. On warm winter days he may think spring has arrived;he gets up and wa[ks around. When he sees that the snow is still thick on the ground, he quickly goes to sleep again.
冬眠不僅僅是睡眠,而是一種沉睡。動物的體溫降到剛好在零攝氏度以上,心臟跳動非常緩慢。人們看到處于冬眠狀態(tài)的動物,常常以為它們是死的:身體摸上去冰涼,可能每5分鐘才呼吸一次。冬眠的動物感覺不到任何疼痛。你可以摸它,拉它的尾巴,也不能使它動一動或醒過來。當(dāng)它處于冬眠狀態(tài)時,甚至可以長時間地生活在有毒空氣中而無任何不良后果。
用這樣的方式越冬,動物可以睡過整個冬天。你或許會覺得奇怪,它好幾個月不吃東西,怎么活過來的呢?可以從兩方面的事實(shí)中得到答案。第一,在夏秋季節(jié),動物體內(nèi)儲存大量的脂肪。第一是與食物對身體的主要用途,即食物供給身體活動所需的能量有關(guān)。我們已經(jīng)知道,冬眠的動物把活動量減少到大大低于一般的水平。甚至心肺的活動量也大大減少了。冬眠的動物幾乎沒有什么活動,幾乎也不消耗什么能量。因此它也幾乎不需要什么食物。
有些動物,包括有些熊,只是半冬眠。就是說,每到冬天它就睡覺,不過他們睡得不那么沉,因?yàn)樗麄儗贉匮\(yùn)動,所以體溫不下降。在秋天,熊吃了又吃長得真是肥極了。它身上的毛也長得更長了,很快全身就包滿了一層厚厚的脂肪和毛。到了11月,它找個地方躺下睡覺了。在冬天暖和的日子里,它可能以為春天已經(jīng)來到了,便起來四處走走,當(dāng)它看到地上積雪仍然很厚時,它很快又去睡了。
關(guān)于冬天的動物的英語美文篇二
American researchers spent two summers studying polar bears on the Arctic sea ice. They found that sea ice, where polar bears spend much of their lives, is melting faster than experts predicted it would. The researchers say this change in the animals' home territory is threatening their survival.
美國科研人員用了兩個夏天研究生活在北極海冰上的北極熊。他們發(fā)現(xiàn),海冰正在快速地融化,比專家預(yù)測的還要快,而北極熊一生中的大部分時間都是在海冰上度過的??蒲腥藛T說,發(fā)生在北極熊家園領(lǐng)域內(nèi)的變化正在威脅著它們的生存。
The scientists published a report on their study in the journal Science. The report says polar bears face a difficult future unless countries reduce air pollution.
這些科學(xué)家在《科學(xué)》雜志上發(fā)表了一篇跟他們的研究相關(guān)的報告,該報告聲稱,除非各個國家減少空氣污染,否則北極熊的未來會非常嚴(yán)峻。
Polar bears live on the ice. It is where they hunt, mate and raise their young. But a team of researchers has found that the animals' ice habitat is warming up, and shrinking.
北極熊生活在海冰上。他們獵食、交配、生兒育女,處處離不開海冰。但是,一個科研團(tuán)隊(duì)已經(jīng)發(fā)現(xiàn),北極熊的海冰棲息地正在變暖和萎縮。
The team was from the University of Wyoming. Its members worked in the Arctic between 2008 and 2010. Merav Ben David was among the researchers. She says they learned that polar bears often have trouble finding food. She says the lack of food can affect their mental health.
這個科研團(tuán)隊(duì)來自懷俄明大學(xué),團(tuán)隊(duì)成員在2008年到2010年之間對北極進(jìn)行了研究。梅-本-傣威是成員之一。她說他們發(fā)現(xiàn)了北極熊常常在尋找食物上陷入困境,而缺乏食物會影響他們的心理健康。
"So if shortening of the spring hunting season, lengthening of the summer season where they are food-deprived and still experiencing difficulties in getting food in the winter, polar bears are stressed physiologically."
“因此,如果用于獵食的春季正在變短,而食物短缺的夏季正在變得漫長,冬季尋找食物又面臨困難,北極熊的身體就會無法忍受。
Ms. Ben David says if the animals do not eat enough food in the spring, they are in poor health when winter arrives.
本-傣威女士說,如果這種動物春季進(jìn)食不夠充足,當(dāng)冬天到來時,它們就會處在不健康的狀態(tài)中。
The researchers traveled on helicopters and ships. They captured more than 20 polar bears, and tested their blood. Before releasing the animals, the researchers equipped them with devices to measure temperature. They then followed the movement of the polar bears on ice and on land.
科研人員的科研之旅是在直升機(jī)和輪船上度過的。他們捕捉了二十多頭北極熊,檢測了它們的血液。在它們身上安裝了測量溫度的設(shè)備后,他們釋放了這些動物。接下來,他們對北極熊在海冰上和陸地上的行動軌跡進(jìn)行了跟蹤考察。
Other studies had suggested that the bears could deal with a lack of food in the summer by reducing their activity -- like the animals do when they hibernate in the winter. But Ms. Ben David says the researchers discovered that did not happen.
曾經(jīng)有其他研究認(rèn)為,通過減少活動,北極熊能夠應(yīng)對夏季食物的匱乏——就如同冬季冬眠一樣。但是,本-傣威女士說,這種情況不會出現(xiàn)。
"We found that polar bears -- like their nearest relatives the brown bears -- are incapable of reducing their metabolic rate to the level that we see during winter hibernation. So there are limits on how long they can go without feeding in the summer."
“我們發(fā)現(xiàn),類似于它們最近的近親棕熊一樣,北極熊是無法把它們的代謝率降低到我們所知的冬季冬眠時的標(biāo)準(zhǔn)的。所以,夏季沒有食物,會影響北極熊到底能走多遠(yuǎn)。
Ms. Ben David says 20,000 to 25,000 polar bears live in the Arctic. She says the world should take action to protect them.
本-傣威女士疾呼,現(xiàn)在的北極,只有兩萬到兩萬五千頭北極熊,為了保護(hù)它們,全世界都應(yīng)展開行動。
"If we want to be responsible citizens of this planet, we have to do everything in our power to stop, reverse the trend of sea ice loss."
“如果我們想成為這個星球上勇于擔(dān)責(zé)的公民,我們必須采取一切措施阻止、改變海冰減少的趨勢。
She says countries must work to limit the greenhouse gases that studies have linked to rising temperatures. She says if that does not happen, polar bears could one day disappear from our planet.
她說,所有國家都必須投入到限制溫室氣體排放的工作中來,因?yàn)闇厥覛怏w會引起氣候變暖,如果不這樣做,北極熊遲早會從地球上消失。
